Definitions

  • the present disclosure relates generally to electronic locks; in particular, this disclosure relates to an electronic lock with a misalignment scoring system. In some aspects, this disclosure provides a method of testing for misalignment issues in a lock's installation.
  • Electronic locks are well known. Some electronic locks operate in conjunction with an access control system, such as a home automation or home security system, while others operate in a stand-alone manner. Many electronic locks, such as electronic deadbolts, include a bolt that is driven by a motor between a retracted (unlocked) position and an extended (locked) position.

  • references in the specification to "one embodiment,” “an embodiment,” “an illustrative embodiment,” etc., indicate that the embodiment described may include a particular feature, structure, or characteristic, but every embodiment may or may not necessarily include that particular feature, structure, or characteristic. Moreover, such phrases are not necessarily referring to the same embodiment. Further, when a particular feature, structure, or characteristic is described in connection with an embodiment, it is submitted that it is within the knowledge of one skilled in the art to effect such feature, structure, or characteristic in connection with other embodiments whether or not explicitly described.
  • items included in a list in the form of "at least one A, B, and C” can mean (A); (B); (C); (A and B); (A and C); (B and C); or (A, B, and C).
  • items listed in the form of "at least one of A, B, or C” can mean (A); (B); (C); (A and B); (A and C); (B and C); or (A, B, and C).
  • an electronic lock is provided with a misalignment scoring system that indicates a level of interference experienced by the bolt as it moves between its extended and retracted positions.
  • the misalignment score provides direct feedback during lock installation or when a user activates the misalignment test. The score enables the user or installer to take action to improve the lock's performance, which could extend the battery life and improve operation of the lock.
  • Figure 1 is a front view of a door, which could be an interior or exterior door.
  • the door 100 has a lockset 102 with a handle 104 and an electronic deadbolt 106.
  • the electronic deadbolt 106 is shown solely for purposes of example and this disclosure applies equally to other types of electronic locks with a bolt.
  • a door jamb 108 is adjacent the door 100.
  • the door 100 is shown solely for purposes of example and this disclosure applies equally to other types of doors that utilize a deadbolt.
  • the electronic deadbolt 106 includes an exterior assembly 200 and an interior assembly 202.
  • the electronic deadbolt 106 includes a bolt 204 that is selectively extended/retracted to lock/unlock the door 100 with a motor 300 ( Figures 3 and 4), depending on whether the user has locked/unlocked the electronic deadbolt 106.
  • Examples of electronic deadbolts with motors that move a bolt between extended and retracted positions are described in U.S. Patent No. 9,024,759 filed March 14, 2014 for a "Wireless Lockset with Integrated Antenna, Touch Activation, and Light Communication Method" and U.S. Application Publication No. 2014/0250956 filed February 25, 2014 for an "Electronic Deadbolt," both of which are hereby incorporated by reference.
  • the bolt 204 is in the extended position in which the bolt 204 extends through a strike plate 208 into a side bore 206 in the door jamb 108. If the bolt 204 is misaligned, interference from the door jamb 108 and/or strike plate 208 as the bolt 204 moves between its extended and retracted positions could negatively impact performance of the electronic deadbolt 106. In addition to misalignment of the bolt 204 due to the door jamb 108 and/or strike plate 208, if the side bore 206 is not of constant width there can be an increasing sideload as the bolt 204 extends into the side bore 206.
  • the interference could require increased torque from the motor 300 to overcome the side load of the door jamb 108 and/or strike plate 206, which would reduce battery life. If the interference from the door jamb 108 and/or strike plate 206 is sufficiently bad, this could completely prevent the motor 300 from driving the bolt 204.
  • the electronic deadbolt 106 includes a misalignment scoring system that rates the level of interference with a lock misalignment score. By using the lock misalignment score during installation (or later when desired), a misalignment can be rectified and performance of the electronic deadbolt 106, including battery life, can be improved.
  • Figures 3 and 4 are block diagrams showing certain electrical components of an example electronic deadbolt 106.
  • Figure 3 shows an illustrative embodiment of a standalone configuration
  • Figure 4 is an example embodiment of a networked configuration.
  • the electronic deadbolt 106 includes a motor 300 for driving the bolt 204 between its extended and retracted positions.
  • a controller 302 controls actuation of the motor 300 to drive the bolt 204.
  • the controller 302 could actuate the motor 300 to drive the bolt 204 to the retracted position responsive to a user entering a proper authentication code.
  • controller 302 could actuate the motor 300 to drive the bolt 204 to the extended position responsive to receiving a command from a user to lock the electronic deadbolt 106.
  • the controller 302 may be embodied as any type of processor capable of performing the functions described herein.
  • the controller 302 may be embodied as a single or multi-core processor(s), digital signal processor, microcontroller, or other processor or processing/controlling circuit.
  • the electronic deadbolt 106 includes a misalignment scoring system
  • the misalignment scoring system 304 is configured to determine a lock misalignment score that is based, at least in part, on a level of interference to movement of the bolt 204 between its extended and retracted positions.
  • the term "lock misalignment score" is broadly intended to encompass any rating of interference with movement of the bolt between its extended (locked) and retracted (unlocked) positions, including but not limited to interference caused by installation issues and/or internal issues with the electronic deadbolt that interfere with movement of the bolt.
  • the interference could be caused by the door jamb and/or strike plate due to installation issues and/or interference internal to the electronic lock that interferes with movement of the bolt even if the alignment with the door is good.
  • the lock misalignment score could be, but is not necessarily, a numerical value.
  • the lock misalignment score could be "low,” “medium,” or "high.”
  • the lock misalignment score could be a graphical representation, audible indication and/or haptic feedback that indicate a level of interference.
  • the lock misalignment score could be tied to lock functionality. For example, a score of "1" could signify one month of battery life, while a score of "12" could signify twelve months of battery life.
  • the misalignment detection unit 306 is configured to detect a level of interference in bolt movement between its extended and retracted positions. There are several means by which a level of interference in bolt movement could be detected. For example, the misalignment detection unit could measure at least one physical characteristic of the motor while driving the bolt between the extended position and the retracted position. In some embodiments, the misalignment detection unit 306 could include an electrical sensor to detect a current, voltage, and/or power drawn by the motor 300 in driving the bolt 204 between its extended/retracted positions. In other embodiments, the misalignment detection unit 306 could include a torque sensor to detect an amount of torque exerted by the motor 300 to drive the bolt 204 between its extended/retracted positions.
  • the misalignment scoring unit 308 is configured to take the data measured by the misalignment detection unit 306 and determine a lock misalignment score. For example, a current, voltage, power and/or torque measurement made by the misalignment detection unit 306 could be compared with a baseline measurement, which would represent no interference, and the lock misalignment score could increase as the current, voltage, power and/or torque needed by the motor 300 to drive the bolt 204 increased from the baseline measurement. There are numerous ways of establishing a baseline measurement. In some embodiments, the baseline measurement could be established during installation by actuating the bolt 204 between its extended and retracted positions with the door open.
  • the baseline measurement could be established during production of the electronic deadbolt 106 during factory calibration of the lock and stored in memory.
  • the baseline measurement could be established during an initial handing process of the electronic deadbolt 106 when the lock is first installed.
  • the baseline measurement could be a programmed constant that was established through empirical measurements.
  • the comparison with the baseline measurement could be made on absolute measurements. For example, a peak current, voltage, power and/or torque level could be compared with that of the baseline measurement to determine a lock misalignment score.
  • a rate of change of the current, voltage, power and/or torque measurement could be used to determine a level of interference.
  • the motor there may be different current, voltage, power and/or torque levels during the operation of the motor through various phases of driving the bolt (e.g., starting motor, driving bolt, stopping motor, etc.).
  • the measurements during various phases of the motor's operation could be compared with the baseline to determine the lock misalignment score.
  • Figure 3 shows an embodiment of a stand-alone electronic deadbolt 106 with a user interface 310 on the electronic deadbolt 106.
  • Figure 4 shows an example embodiment in which at least a portion of the user interface 310 is offloaded from the electronic deadbolt 106 onto a separate device.
  • the electronic deadbolt 106 includes a communication unit 400 that communicates with a computing device 402, which provides at least a portion of the user interface 310.
  • the communication unit 400 may be configured to use any one or more communication technology (e.g., wired or wireless communications) and associated protocols (e.g., Ethernet, Bluetooth®, Wi-Fi®, WiMAX, Zigbee®, Z-Wave®, etc.) to effect such communication.
  • communication technology e.g., wired or wireless communications

Abstract

L'invention concerne une serrure électronique dotée d'un ensemble serrure qui comprend un pêne mobile entre une position déployée et une position rétractée. La serrure électronique comprend un moteur conçu pour entraîner le pêne entre la position déployée et la position rétractée. Un dispositif de commande est conçu pour commander l'actionnement du moteur pour déplacer de façon sélective le pêne entre la position déployée et la position rétractée. La serrure électronique comprend une interface utilisateur conçue pour fournir en sortie des informations concernant la serrure électronique. Un moyen d'évaluation de désalignement permet de détecter toute interférence avec le mouvement du pêne entre la position déployée et la position rétractée et de déterminer un score de désalignement de serrure en fonction de l'interférence détectée. L'interface utilisateur identifie le score de désalignement de serrure.
